加入者情報の更新処理を行うことを特徴とする。According to the present invention, there is provided a mobile communication switching center backup file creation system, comprising: a mobile communication terminal registered in one of a plurality of mobile communication switching centers; When a subscriber moves to another mobile switching center, a subscriber number of the other mobile switching center is assigned, and a subscriber who is required for call connection service from the self-registered mobile switching center is assigned. In a mobile communication network in which automatic roaming is performed by transferring information, the mobile communication switching center is duplexed so that one of the main processing units operating in synchronization is put into an isolated operation mode and the other is shut down, and the shutdown is performed. The main processing device that has output the contents of the main storage device of its own system to the external storage device creates a backup file, and the main processing device in the single operation mode is moved from another mobile switching center. And performing came the updating of the subscriber information of the mobile communication terminal subscriber.

が更新される。The main processing units 10 and 11 of the system 0 and system 1 of the mobile communication switching system are duplicated and perform synchronous operation. One of them is active and the other is operated in standby. The contents of the main storage devices 20 and 21 of both systems are updated only with the processing result of the active system so that the contents of 21 match.
